Bruce,
I've read your test cases quite carefully prior to any of my emails on
this thread, quite carefully, I might add. I suggest you re-read what
you wrote, preferably with no pre-conceived notions. There are a number
of implicit factors, not explicitly stated, and certainly not in one
document. Just to show how it could be interpreted differently, I'll add
my own comments:

Earliest showing
Verified.
With "Reschedule Higher Priorities" turned off, a (2)higher priority(2)
show
that could be postponed to a later showing will record even if a lower
priority title will not be recorded as a result. In this example,
Nova at 8pm is marked to record and SportsCenter marked as a conflict:
Title - Subtitle Chan ChID Day Start End S C I O N Pri
American Idol 5 1005 24 20:00-21:00 1 2 2 0 2 1
Nova - "Spies That Fly" 10 1010 24 20:00-21:00 1 1 1 0 1 2
SportsCenter 30 1030 24 20:00-21:00 1 0 0 0 C 0
Nova - "Spies That Fly" 10 1010 25 01:00-02:00 1 0 0 0 E 2

(1) Conflict resolution in the "aggregate" tuner case (taking into
account all available tuners), or on a specific tuner?
(2) Higher priority? Where does this "higher" priority come from,
especially when a mythtv user did not "explicitly" designate a priority?
(A "casual" reader would not know that there is an "implicit" priority
ranking based on the kind of recording, say "one-time" vs. week slot vs.
"any channel/any time." A fact which David Engle made clear only a few
posts prior, way after you published your "test cases" a few posts after
this thread first started.)

Umm, perhaps in *your* testing, but certainly not in mine. I schedule
quite a number of programs on PBS, and there are at least 4 distinct PBS
stations in my area. Repeats for these programs are a common
occurrence. This has (almost) nothing to do with with how heavily you
schedule recordings on myth, but rather has to do with viewing habits,
and prevalence of stations that happen to show repeats in your
geographic area. I can tell you w/o exaggeration I need to to manually
override at least 70% of all my recordings, if I use the myth .14
scheduler logic.
And when the time comes when ATSC/HDTV becomes "fully supported" within
myth, this problem will only exacerbate.
The intent here is not to brass you off, but to reiterate the need for a
document that spells all this out, for everyone in mythtvland to have a
proper grasp of multiple tuner scheduling logic. All the usage
cases/scenarios documented/explored in one comprehensive document, not a
scatter-gun approach like we've been dong on this thread, and a prior
thread.
